I'm interested in seeing what they add. I like playing around with my girlfriend's iPad, but I'm still hesitant to get one myself as it doesn't quite do everything I want with a tablet. But neither do the Androids yet. I basically want something that's closer to a tablet PC, but is thin and light and gets great battery life like the iPad. Not those convertable laptop tablets or the bulky slate PCs of the past.
I don't need full PC functionality power wise, just simple things like a drag and drop file and folder system like on Windows or Mac, stylus support etc. to make it both a work tool and a multimedia toy.
